What is Admiral?

Admiral™ is a highly scalable and very lightweight Container Management platform for deploying and managing container based applications. It is designed to have a small footprint and boot extremely quickly. Admiral™ is intended to provide automated deployment and lifecycle management of containers.

This container management solution can help reduce complexity and achieve advantages including simplified and automated application delivery, optimized resource utilization along with business governance and applying business policies and overall data center integration.

Admiral is a service written in Java and based on VMware's Xenon framework. This service enables the users to:

• manage Docker hosts, where containers will be deployed
• manage Policies (together with Resource Pools, Deployment Policies, etc.), to establish the preferences about what host(s) a container deployment will actually use
• manage Templates (including one or more container images) and Docker Registries
• manage Containers and Applications
• manage other common and required entities like credentials, certificates, etc.

Getting started

Running Admiral

There are three ways you can start Admiral:

1. Run container image

docker run -d -p 8282:8282 --name admiral vmware/admiral

Open http://<docker-host-IP>:8282 in browser...Configure Docker Host

Note Due to the significant amount of logs generated it is advisable to include docker log parameters:

--log-driver=json-file --log-opt max-size=1g --log-opt max-file=10

This sample parameters added to docker run command will keep 10 files of 1GB each. Tune according your needs.

2. Download the published build archive, you can find it in 'Downloads' section here.

java -jar admiral-host-*-uber-jar-with-agent.jar --bindAddress=0.0.0.0 --port=8282

Open http://127.0.0.1:8282 in browser...Configure Docker Host

3. Clone the repo and build locally. Detailed instructions about building locally can be found in the Admiral developer guide:

• Building the Admiral agent first (to achieve smaller image file size an LZMA2 compression is used, you need xz utils )

cd container-images/admiral-agent
make buildall

• Building the Java project

mvn clean install -DskipTests

• Run the project

java -jar host/target/admiral-host-*-jar-with-dependencies-and-agent.jar --bindAddress=0.0.0.0 --port=8282

Open http://127.0.0.1:8282 in browser...Configure Docker Host

Building the code

mvn clean install
